Solved Unins000.Msg Missing And Other Problems

I friend wanted to remove spyware clear, which is malware. I went into the programs and features area, and tried to uninstall it. I got the “unins000.msg missing”, but I also got the option to remove the program from the list. For some reason I chose to do so. Because the uninstall file is not working I can’t uninstall it by any normal means. I have the revouninstall program, but it can not find it, because it is no longer listed.

I also do not know how to add it back to the list.

I also tried Malware Bytes, but the computer is so slow that after 6 hours I was still in the prescan stage. I think this will work, but I am trying to avoid doing it this way if possible.

Thanks

PS: The computer is Windows 7, if it matters.
